BB148,115 - NXP - Datasheet.Live

1. Product profile

1.1 General description

The BB148 is a variable capacitance diode, fabricated in planar technology, and

encapsulated in the SOD323 (SC-76) very small SMD plastic package.

The excellent matching performance is achieved by gliding matching and a Direct

Matching Assembly (DMA) procedure. The diodes are delivered on tape in several

matched groups and are also available unmatched upon request. The unmatched type,

BB158 has the same specification.

1.2 Features and benefits

Excellent linearity

Excellent matching to 1 % DMA

Very small SMD plastic package

Cd(28V): 2.6 pF; Cd(1V) to Cd(28V) ratio: 15

Low series resistance.

1.3 Applications

Electronic tuning in VHF television tuners, band B up to 460 MHz

Voltage Controlled Oscillators (VCO).
